    Abstract 摘要

    ​This study presents results of the first comprehensive research on ecotoxic trace metals (Cd, Pb, Cu and Zn) in aquatic anchialine ecosystems. Data show the influence of hydrological and geological characteristics on trace metals in highly stratified anchialine water columns.

    這項研究提出了關於微量生態毒性金屬的第一次全面研究的結果: ( 激光片、鉛、銅、鋅)等在水生的anchialine生態環境。數據顯示:水文對高度分層的anchialine水柱的微量金屬和地質特徵的影響。

    anchialine:安奇亞線路

    Pb: 鉛 plumbum的縮寫.

    Cu: 銅

    Zn: [化]鋅

    ecosystems:生態系統

    Distribution of Cd, Pb, Cu and Zn in two anchialine water bodies, Bjejajka Cave and Lenga Pit in the Mljet National park, Croatia were investigated seasonally from 2006 - 2010.

    從2006 - 2010, 克羅地亞進行了季度調查;在個anchialine水體, 分别在姆列特國家公園和bjejajka洞穴和朗加坑, 其Cd、鉛、銅和鋅的分佈。

    Behaviour and concentrations of dissolved and total trace metals in stratified water columns and metal contents in sediment, carbonate rocks and soil of the anchialine environment were evaluated.

    以溶解沈積層展現:在分層的水體狀和總微量金屬含量的濃度, 碳酸鹽岩和土壤的環境, 評價為:anchialine水體的濃度與鄰近的海水明顯增高。

    【 生字 】

    stratified: 分層的

    concentrations:濃聚物= 沈積層

    Trace metals:微量元素

    evaluated:估價的

    Trace metals and dissolved organic carbon (DOC)

    and dissolved organic carbon (DOC) concentrations in both anchialine water columns were significantly elevated compared to adjacent seawater. Zn and Cu concentrations were the highest in the Lenga Pit water column and sediment.

    數據控制工作室工作人員:微量金屬溶解的有機碳和溶解的有機碳沈積物的元素,兩個anchialine的水體的濃度, 相對地是明顯較為高的。在主要陸源“bjejajka洞穴”的水體中發現,鎘濃度顯著升高(可達0.3µg L-1)。與鄰近的海水, 鉛和銅的濃度沈積物, 倫加坑水體是最高的。

    DOC: 數據控制工作室工作人員(=Data Optimizing Computer)

    elevated:提高的

    organic carbon:有機碳

    concentrations:濃聚物

    adjacent:鄰近的

    stratified water column 分層水體

    sediment:沉澱物

    Laboratory analysis revealed that bat guano was the major source of cadmium in Bjejajka Cave. Cadmium levels in Lenga Pit, which lacks accumulations of bat guano, were 20-fold lower.

    實驗室分析顯示,蝙蝠糞是在在bjejajka洞穴鎘的主要來源, 在倫加坑的鎘, 那裡缺乏蝙蝠糞堆積, 水平低於20倍。

    【 生字 】

    cadmium:鎘

    Moreover, low metal amounts in carbonate rocks in both caves, combined with mineral leaching experiments, revealed that carbonates play a minor role as a source of metals in both water columns. We observed two types of vertical distribution pattern of cadmium in the stratified anchialine Bjejajka Cave water column.

    此外, 低金屬量的碳酸鹽岩在這兩個洞穴中, 結合礦物浸出的實驗,揭示了碳酸岩扮演的一個小角色。作為金屬的來源; 在這兩個水柱體。我們觀察到兩種類型在分層的anchialine和bjejajk洞穴水鎘, 呈垂直的分佈格局。

    At lower salinities, non-conservative behaviour was characterized by strong desorption and enrichment of dissolved phase while, at salinities above 20, Cd behaved conservatively and its dissolved concentration decreased. Conservative behaviour of Cu, Pb, Zn and DOC was observed throughout the water column. After heavy rains, Cd showed reduced concentration and uniform vertical distribution, suggesting a non-terrestrial origin. Under the same conditions, concentrations of total and dissolved Pb, Cu, Zn and DOC were significantly elevated.

    在低鹽度和非常保守行為具有較強的吸附和溶解相而富集;在鹽度20以上,CD的表現保守和溶解濃度降低。在暴雨過後, 整個水體展現保守的行為,銅、鉛、鋅的濃度降低和呈現出均勻的垂直分佈。這意味著來自非陸地的源頭, 在相同條件下, 鎘的 總溶解態和沈積物的鉛、銅、鋅、的濃度均顯著升高。

    【 生字 】

    salinities: 鹽度

    non-terrestrial:非陸地的

    origin:始源

    Variations of trace metal vertical distributions in anchialine water columns were caused by large inputs of fresh water (extraordinary rainy events), and were not influenced by seasonal changes.

    在anchialine水柱微量金屬的垂直分佈變化, 和大量新鲜水的流入,導致了(異常多雨的情況),並且不受季節變化的影響。
